DETAILED DESCRIPTION OF THE DRAWINGS AND THE PRESENTLY PREFERRED EMBODIMENTS

The visual warning devices of the present invention are designed to be free-standing, or vehicle mountable, advance warning safety notification devices that can be used by first responders and other authorized roadway personnel to enhance temporary traffic control zones conspicuity.

The design of the visual warning devices of the present invention is based on a rectilinear arachnid concept that has been scientifically proven to break inattentional blindness, whether or not an individual is afraid of spiders (New et al., Spiders at the Cocktail Party: An Ancestral Threat that Surmounts Inattentional Blindness. Evolution and Human Behavior, 36, 165-173, 2012).

The visual warning devices of the present invention provide a greater overall physical presence than currently available solutions as well as an opportunity for advanced warning over greater distances, which is extremely beneficial in low light/poor weather conditions. The ability of the visual warning devices of the present invention to increase attentional awareness provides drivers with the ability to quickly identify and appropriately react prior to traffic transition areas so as to reduce bottlenecking, traffic jams, and or secondary accidents. In the event of a temporary traffic control zone breach, contact with visual warning devices of the present invention can alert drivers prior to making contact with pedestrians or vehicles, thereby preventing further damage, injury or loss of life. The visual warning devices of the present invention can be made from materials that are impact resistant, environmentally friendly, reusable, recyclable, and non-toxic to humans and animals.

The visual warning devices of the present include a support base, a support post that extends upward from the base, a head supported at the top of the support post and a plurality of arms that extend outward from the head.

The support base can be a free standing, foldable tripodal or quadrupedal (or greater-legged) base that can be translucent and illuminated, weighted and/or staked and configured to have a low center of gravity.

The support post can be configured to be height-adjustable in any convenient manner, including being telescopically height-adjustable. The height range of the support base can be from about 3 to 6 feet, or taller, as desired.

The head is a lightweight wind-resistant illuminated/translucent structure that is attached to the top of the support post. The head is sturdy enough to support the arms and can be removably attached to the top of the support post if desired for use without the base and support post. As described below, a wireless signal receiving unit can be provided in the head.

The arms comprise folding or telescopically retractable/deployable high-wind resistant and weather-proof structures which are affixed in pairs of 2 radiating outwardly from the head. Each arm can be deployed and adjusted to a length of 2.5 to 5 feet or greater, as desired. There are a total of 8 arms that can be repositioned from a storage configuration to a deployed position in one simple sliding motion. The arms can be translucent and illuminated by lights provided in the head or by light transmitted thought the head.

The visual warning devices of the present invention can be illuminated as discussed below. In some embodiments the front, back and base can be separately illuminated (or illuminated in different colors) to avoid confusing and or distracting those outside the intended viewing aspect when oncoming or opposing directions of viewing are involved.

The visual warning devices can include onboard and/or wireless control circuits to allow activating and deactivating illumination and selecting appropriate colors and a selection of illumination sequences.

The visual warning devices can be powered by an onboard battery or battery pack provided with a charging circuit and a solar charging accessory, if desired. In addition, the visual warning devices can include tracking/location devices that allow, for example RFID tracking and/or GPS locating.

The visual warming devices are made from waterproof and high impact resistant materials and can be designed for use in extreme temperatures/weather.

The visual warning devices can be manipulated into storage configurations and stored in small footprint storage bags/containers for simple storage in a number of vehicles and environments. Sets of two or more visual warning devices can be stored together in larger storages bags/containers and alternatively coupled together for storage.

In alternative embodiments the head and/or arms can be provided with magnetic mounts for vehicle mounting or other alternative deployment, including attachment to existing, nearby signage.

The standing, foldable tripodal or quadrupedal (or greater-legged) base allows for ground level illumination when translucent, reflective, or otherwise illuminated, and provides sufficient stability in a number of conditions. Providing flat feet on the legs of the base allows for applying stabilizing weight to the base using a number of objects, aside from the available standard base weights, capable of withstanding gusts and substantial wind speeds. The wind-resistant design of visual warning devices assists in preventing the accumulation of precipitation and debris. It has been determined that desired stability of the visual warning devices can be achieved when 80% of their weight in the lower ¼ of their construction. A low center of gravity allows for minimal base weight to be added for exponentially increased stability when necessary. It is also possible to stabilize the visual warning devices by securing them with stakes that are driven into the ground upon which the visual warning devices are position, including paved and unpaved surfaces.

In some embodiments, the legs of the support base can be configured to deployed by holding the bases upright and releasing the legs so that they deploy under the force of gravity. Such deployment will allow a user to walk and deploy multiple units easily.

The visual warning devices can be sufficiently waterproof to be used in the event of flooding/flash flooding and can be attached to existing signage and other anchored structures along/in the roadway in such circumstances. Use during flooding can help signify water levels, block flood-zones from automotive traffic, and serve as beacons in situations where watercraft/aircraft are the only means of transportation.

In some embodiments, the heads of the units can be configured to pivot 90 degrees to display for easy aerial detection. Optional magnetic bases can be provided that replace the foldable tripodal or quadrupedal (or greater-legged) bases which will allow for vehicle top-side mounting accommodating a variety of needs. Alternatively, the head with the arms attach may also be magnetically attached to the side of any metal surface. Alternatively a mounting bracket such as a hook or L-shaped bracket can be provided on the back of the head to mount the head and arms on to a vehicle of other structure.

In addition to the tracking/location devices mentioned above, the visual display devices can include cameras integrated in bases (or on the heads) which can be set to auto-record upon deployment and keep footage for a designated amount of time.

Lights located in the base, support post and/or head can be used to illuminate the visual warning devices. The user also has the ability to pulse the lights in a desired color pattern such as between, red-orange, yellow-green, blue, white, amber, and other colors.

The visual warning devices can be used in a unidirectional manner to control light output and direction when required/preferred (e.g. temporary event queues/intersection traffic/roadway detours). Remote, wireless operation features will keep officers (and other authorized personnel) safe and out of harm's way while directing traffic. Sets of the visual warning devices can be automatically synced to illuminate in sequential series.

As compared to current devices such as traffic cones or barrels, the tall profile of the visual warning devices of the present invention increases overall conspicuity and can be used to signify a roadway disruption (in heavy traffic) prior to the temporary traffic control zone (TTC zone) by deploying units on the side of the road that should be avoided.

FIG. 1 is a front view of a visual warning device according to one embodiment of the present invention. The visual warning device shown in FIG. 1 includes a base 1 at the bottom of support post 2 to which a plurality of legs 3 are pivotally attached so that the legs 3 can be deployed to radiate outward from the base 1 as shown to support the support post 2 in an upright position. The legs 3 can be temporarily secured in the deployed configuration shown in FIG. 1, by inserting pins (not shown) through the base 1 and legs 3 near the pivot points of the legs 3, by providing engaging structures such as spring detent elements, sleeves on the legs 3 that can be slid over the pivot points, clips that can be clipped over the pivot points, etc.
